"Setting Putty" for machine installation?

[cadcoke5]

I may be imagining this sort of thing, and my search of the internet and McMaster has not turned up anything...

An analogy to this is pouring a skim coat of cement over an irregular floor before you lay tile.

I am mating two machine assemblies, about the size of desks. One of the assemblies is on casters, while the other is fixed. Exact alignment of the two assemblies is not necessary, but repeatability is.

There will be a machined plate installed on each of them with alignment pins. At first these two plates will be screwed to the non-rolling assembly. Then, by a series of through holes, I will screw the 2nd plate to the rolling assembly, and release that same plate from the non-rolling assembly. The result should be a pair of plates that are aligned face-to-face. Hopefully, the two will re-align after rolling the two assemblies apart and back together.

I would like to put some sort of setting putty between the 2nd plate and the rolling assembly. Ideally this would be something that is both dimensionally stable as it sets, and removable if I ever have to re-install this machine on a new floor.

Does such a product exist? Am I just using the wrong search term?

Machine grout -- find a good machine rigging company whey will be familiar with it

Check your caster loads - they can sometimes bust up the best concrete in the world...

Thanks for the replies. Regarding caster load, the weight of the machine is only about 200lbs. Still, I hadn't considered the idea of the casters wearing into the surface over time. But, it is actually not an issue here. We wanted to even out the surface the wheels ride on a bit, so we will have some steel bar fixed to the floor to provide a rolling surface, so that should provide a good base for the casters.

If it only weighs 200 lbs and you are putting it on some kind of steel rail - go to Lowes or Home Depot and get some floor leveling compound. Hell I weigh 200 lbs and it works for me!!
